1.2 Three test methods are included here that account for the special characteristics of different petroleum products and apply to the following distillation ranges:

Test Method

Petroleum Products

Boiling Range, °C (°F) (approximate)

A

Light Distillates

15–260 (60–500)

B

Middle Distillates

200–370 (400–700)

Gas Oils

370–510 (700–950)

C

Residua

510+ (950+ )

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. The preferred units are mass %.

1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see Sections 6.2 and 6.4.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
